data to improve effectiveness and efficiency.

BRIEF DESCRIPTION OF THE INVENTION

[0004]A medical data collection device is comprised of a head unit and a
base unit. The head unit collects patient data and transmits the data to
the base unit. The base unit captures, stores and processes the data. A
display on the base unit shows the captured data and allows the user to
control the data. In a specific embodiment, the invention includes
devices and methods for remotely diagnosing an ear infection using mostly
off-the-shelf components.

[0011]FIG. 7 depicts a schematic of an embodiment of the system for
remotely diagnosing an ear infection using mostly off-the-shelf
components.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0012]A medical data collection device is outlined in FIG. 1. A medical
professional (not shown) uses a hand-held head unit 100 to collect data
from a patient. Head unit 100 captures data including visual, audio,
echogram, electrocardiogram, and lung function data. The data is
processed into a digital signal and transmitted to base unit 200. Base
unit 200 displays the data and stores the data in memory. Base unit 200
may also transmit the data to an outside computer or computer network
300.

[0013]Data transfer between the head unit and base unit is by means of
radio signals, so that the medical professional has maximal freedom to
manipulate the head unit. Data transfer between the base unit and the
outside computer may be wireless or wired.

[0014]Referring to FIG. 2, the head unit 100 comprises a body 102. A
sensor assembly 104 is attached externally to, or formed continually
with, the body 102. Alternatively, the sensor assembly may be physically
separate from the body and connected wirelessly. The sensor assembly 104
further comprises a sensor or sensors 106 capable of collecting patient
data. An optional fitting 108 allows interchangeable sensor assemblies to
be attached to the body 102. The head unit 100 may include one or more
control triggers or switches 150. Such switches may be used to turn data
capture functions on or off or to changes settings of the head unit,
e.g., zooming a video image. A power supply 140 is included in the head
unit 100.

[0015]Data collected from sensors 106 is transmitted to a processor 120.
Typically the sensors will collect analog data which will be converted to
digital form by the processor. The digital signal is sent to a first
transmitter 130, which sends radio signals including the data to the base
unit 200. In an alternative embodiment, the data may be sent as an analog
signal to the body unit before analog to digital processing.

[0016]The head unit 100 may also comprise one or more displays 160. Such
displays may include lights, video screens and audio speakers.

[0017]FIG. 2 describes the head unit only schematically. The actual
physical implementation of a head unit is typically an ergonomic, light
weight device that can easily be manipulated with one hand, leaving the
user's second hand free. The head unit retains all the functionalities of
the instruments it replaces, with the added benefit of digital data
capture and storage. For example, when in otoscope mode a user can
directly see the ear canal either via the display 160 or a conventional
lens (not shown). Also for example, when in sonogram mode the user can
directly view the data via a display 160 on the head unit or a display
250 on the base unit (shown in FIG. 3).

[0018]Head units with different sensors may differ greatly in physical
form, while retaining the basic functionalities of a head unit as shown
in FIG. 2. For example, an electrocardiogram head may comprises a set of
pads for attaching to a patient's chest, where the sensor assembly
comprises the pads and where the sensor assembly is connected to the body
of the head unit either permanently or detachably. A head unit having a
sensor assembly comprising a fiber optic camera for examining parts of
the body where the sun don't shine will differ greatly in appearance from
the electrocardiographic head. Head unit bodies may also take on a
variety of forms depending on the type of patient data to be gathered.

[0019]Because the physician using the device can always view the patient
data directly, the physician can select optimal conditions for capturing
and storing the data digitally by using a trigger 150. This allows the
physician to position the head unit for optimal data capture, providing
the dual benefits of reducing the need to store redundant or suboptimal
data and to record observations uniformly so that changes in a patient's
condition can be more easily detected by comparisons with previously
stored data.

[0020]Referring to FIG. 3, the base unit 200 comprises a receiver 210
which receives radio signals from first transmitter 130 in the head unit.
Receiver 210 delivers the data to processor 220. Data may be stored to
and retrieved from memory 240. Control panel 230 allows a user to control
the collection and dissemination of data. The panel may also remotely
control the head unit by means of radio signals. One or more displays 250
display live or retrieved data, machine function, and menus of functions
for ease of use. Such displays may include lights, video screens, data
screens and speakers. Control panel 230 and display 250 may be
integrated, e.g., as a touch screen operated by fingers or stylus.

[0021]A prompter 280 may be incorporated into the base unit 200 or
integrated into the outside computer or computer network 300. The
prompter is a computer routine implemented by either hardware or software
or a combination of hardware and software. The main function of the
prompter is to prompt the medical professional to obtain specific data
based upon the circumstances of the patient. The prompter relies upon
patient specific data such as age, sex and weight, as well as flags noted
in previous examinations. In this way the prompter serves certain
functions of current paper medical charts. Using the patient specific
data, the prompter activates a display to provide relevant data and
recommendations to the medical professional. The prompter also uses
patient data to suggest diagnosis and treatment options. A medication
tracker is incorporated into the prompter to record treatment histories
and check for pharmaceutical incompatibilities.

[0023]One or more wide-angle cameras may be included in the system. The
wide angle cameras may be configured as part of the base unit or
separately. If the system is deployed in an examination room, the camera
or cameras may be permanently positioned to record all or part of an
examination. The cameras may be operable by a switch or trigger on a head
unit, to allow the physician to record selected aspects of the
examination.

[0024]The system may include multiple head units or sensors functioning
simultaneously. For example, audio and video heads may be used together,
whether they are configured as multiple sensors in the same head unit or
configured separately.

[0025]The sensors of the head unit may be configured in various ways
without departing from the spirit of the invention. In one embodiment,
many of the sensors are attachable and detachable from the housing 102 by
the use of a fitting 108. In this embodiment, the fitting physically
holds the sensor and also provides connections for transmitting data from
the sensor to the processor 120. Some sensors such as camera, microphone,
and video capture may be permanently integrated into the head unit. In a
configuration with detachable sensors, a head unit package capable of
recording a complete physical examination includes one head unit housing
and a plurality of detachable sensors.

[0026]In another embodiment, a head unit may have all its sensors
permanently incorporated. Such a head unit may or may not include all the
functionalities necessary for recording a complete physical examination.

[0027]In another embodiment, a plurality of head units each includes one
or more sensors. The sensors may or may not be detachable. In this
configuration, a head unit package capable of recording a complete
physical examination includes a plurality of head units. Additional
detachable sensors may also be included.

[0028]When a particular sensor is enabled on a head unit, the head unit
and sensor together may be referred to as a particular type of sensor
head. For example, a head unit with an enabled EKG sensor may be referred
to herein as an EKG head.

[0029]A primary use of the invention is to conduct and record general
physical examinations. Typically such examinations will proceed in a
specific order. A preferred order is head, eyes, ears, nose, throat,
chest/lung, heart, abdomen, genitals, extremities, nervous system, nodes,
skin and spine. The displays (either on the head unit and/or on the base
unit) may be programmed to prompt the physician to record data.
Especially in the case of follow-up examinations where previous symptoms,
conditions or abnormalities have been noted, the system can remind the
physician to record particular data.

[0030]In a preferred mode, a continuous audio stream is recorded during
the general examination. Video may be recorded under the control of the
user.

[0031]Information such as the patient's age, height, weight, blood
pressure, reported symptoms, current medications and treatments may be
recorded prior to or at the outset of a session. Such information may be
recorded in a variety of ways including data uploads or the use of a data
entry device such as a keyboard or voice recognition system. Patient
information and data stored in the system can be used to substitute for
paper records.

[0032]An examination may begin by starting the audio recording. The
purpose of the examination may be stated for the record. While examining
and palpating the head, wide angle video capture may be turned on to
record the technique used. A head unit with a video sensor enabled is
used to examine the eyes. The physician may record the eye examination
with pictures and/or video. A video/otoscope head is then used to examine
and record the condition of the ears, nose and throat. Stethoscope, peak
flow meter and echogram heads are used for the chest, lungs and heart.
Again, the physician records key data into the system. The examination
continues with the physician selecting and using the appropriate heads
and sensors.

[0033]Complete primary patient data is recorded by the end of such a
session. Additionally, the physician may flag certain aspects of the
session for specific follow-up. Such data recorded into the system may be
used, for example, to prompt a patient to schedule a follow-up exam, and
then prompt the physician to pay special attention to certain aspects of
the patient's health during subsequent examinations.

[0034]An initial data collection session, where there is no existing
patient data in memory, begins by an operator initiating the session.
Patient identification information is recorded by the operator and stored
in memory. To make an audio recording of the session, the operator turns
on a microphone. The microphone may be located on the head unit, the base
unit, or separately. The operator may enter audio data (e.g., "18 month
old male patient has presented with symptoms of fever and crying.") which
is stored in memory. To examine the patient's ears, the operator selects
a otoscopic head unit with fiber optic video sensors. The operator
inserts sensor into a patients ear. Once the sensor is in place for
optimal data collection, the operator activates a trigger and a view of
inner ear is captured, displayed for operator on a display, transmitted
to base unit and stored in memory. The examination continues with the
operator selecting and employing sensors as appropriate.

[0035]A subsequent physical examination of a treated patient, where
existing patient data is stored in memory, begins by the operator
entering patient identification into the system. The system recalls the
patient's data from memory and associates the new session with existing
patient records. The prompter will activate a display, reminding the
physician of pertinent details of the patient's previous condition and
treatment. The prompter will further prompt the physician to collect
specific new patient data based upon the previous condition and
treatment. The physician will then collect and record new data, using the
appropriate hand units and sensors.

[0036]The system can also be used for abbreviated tests, such as when only
one or two observations are needed to monitor the patient's condition.

[0037]Analytic functions can be incorporated into the system. For example,
measurements of skin lesions may be recorded by internal scales. The
system may also include features to compare the state of a skin lesion
over time.

[0038]Sensors with advanced analytic functions may also be used.
Spectroscopic, temperature, chemical, and other measurements of various
parts of the body that are highly predictive of particular conditions may
be taken. For example, physical properties of the tongue may indicate
certain diseases.

[0039]The system may include features to aid a medical professional in
monitoring physical conditions over time. For example, the system may
used stored data to prompt the medical professional to repeat earlier
observations. For example, in surveying a patient's moles, the operator
may, during an initial examination, record a flag regarding a picture of
a mole on a patients left upper arm. In a subsequent visit, the system
may prompt the medical professional to record a new view of the same
mole.

[0040]FIG. 4 shows a schematic of the system incorporating a teaching
tool. When a teaching tool is incorporated with the system, the system
includes head unit 100, base unit 200, teaching program 400, control unit
500, and display unit 600. Teaching program 400 uses patient data to
create a visual or graphic display of the patient's physiological
condition. Such patient data includes new patient data collected during
an examination session, existing patient data collected from the patient
during previous sessions, and existing data drawn from a universal
database of normal and abnormal human physiological conditions. The
physician uses the control unit 500 to manipulate the teaching program
400 to access new and existing data to create one or more graphic
displays and display them on a display unit 600. The teaching program 400
is a computer routine implemented by either hardware or software or a
combination of hardware and software. Teaching program 400 may be
included in the base unit 200, or it may be included in an external
computer or computer network 300.

[0041]The teaching tool is intended to facilitate communication and
teaching between physician and patient by assisting the physician to
describe the patient's condition and treatment options. For example, new
patient data gathered with an echocardiographic head may show that a
patient has an enlarged spleen. The physician can use the teaching tool
to demonstrate to the patient their condition and the further tests
needed to identify the cause of the enlargement. Once further tests are
completed and the data is entered into the system, the physician can
again use the teaching tool to demonstrate the cause and the treatment
options.

[0042]The teaching tool is capable of generating many types of graphic
displays including but not limited to patient data such as pictures or
echocardiograms, three-dimensional views of the entire body, three
dimensional views of body systems and organs, representations of cellular
and molecular processes, statistical probabilities of the success of
various treatment regimens, written word descriptions and symbolic
representations. The physician may use control unit 500 to create such
displays, such as by extracting video or activate the teaching program to
execute particular routines. The physician may also use control unit 500
to edit such displays before the patient sees them. The physician may use
an additional display (not shown) for such editing.

[0043]The many advantages of the invention include the preservation of
unambiguous primary patient data. Audio recoding can largely replace
written notes. All patient data can be maintained as an integrated
digital file, providing instantaneous baseline data for aid in the
diagnosis of new symptoms. Patient files can easily be transmitted to
remote locations in case of emergency. Unlimited manipulation of the
patient data for comparisons and consultations is possible. The system
can be installed in a room, or configured as a portable device.
Especially when incorporating a teaching tool, the device aids
communication and teaching between doctor and patient.

[0044]The system is useful for providing an accurate record of a patient's
condition, diagnosis, care and treatment. The main goal is to detect,
record and monitor bio-information in a user-friendly and
patient-friendly way. As a by-product of this approach, the system may
improve doctor and patient relationships by enhancing the time spent in
direct communication and dialoguing.

[0045]The system is also useful for practicing telemedicine. In one
specific embodiment, the device is useful for remotely diagnosing ear
infections.

[0046]Ear infections are a common childhood ailment, often treated by
antibiotics. Typically, diagnosis of such an infection requires a parent
or caregiver to make a special trip with the child for an in-person
examination by a physician. This is often accompanied by waiting with
other sick people in a waiting room. In addition to the inconvenience and
possible exposure to other illnesses, the process also is prone to
overuse of antibiotics, as the physician may be inclined to write a
prescription as a precaution against possible infection. The
doctor-patient interactions in such office visits is simple and
straightforward, and may be substituted for by telemedicine devices and
procedures described herein.

[0047]FIG. 7 depicts a schematic of an embodiment of the system for
remotely diagnosing an ear infection using mostly off-the-shelf
components. Most of the components in this system have been generally
described in other figures, and their corresponding general designations
may be included parenthetically. The system includes a head unit 830 (100
in FIG. 1). The head unit comprises a programmable wireless communication
device (e.g., a cell phone) 832 and an otoscope sensor 834, which are
preferably connected wirelessly, e.g., by a BlueTooth connection. Device
832 may have a display 836 (160) and communicates with a remote base unit
840 (200), which is in turn networked with other devices.

[0048]In practice, the system works by providing a parent or caregiver a
head unit 830, along with training in how to operate it. The parent or
caregiver uses the otoscope sensor 834 to capture images of the patient's
inner ear, including the ear drum. Display 836 may be used to ensure that
useful images are being captured. The images are transmitted to remote
base unit 840 where they are viewed by the examining physician on a
display 850. Alternatively, the images may be transmitted to a second
wireless communication device (e.g., another cell phone) 860 having a
display 862. In this manner, and in conjunction with audio communication,
a physician may diagnose an ear infection almost no matter where the
doctor and patient may be. If indicated, the physician may send a
prescription to the patient (or the patient's pharmacy) without the need
for an office visit.

[0049]Other aspects of the general system may be useful for such
diagnosis. For example, the physician may use display 850 or device 860
to retrieve the medical records of the patient. Diagnostic routines
embedded in the system may guide the physician in his or her diagnosis.
Other sensors may be used by the patient or caregiver to capture addition
data for the physician's diagnosis. Also, the diagnostic session data is
stored in the patient's medical record for further use.

[0050]In one aspect, the invention is a device including a head unit plus
a base unit. The device is used for collecting medical data from a
patient. The device comprises a base unit and a head unit, where the base
unit comprises a transceiver, a control panel, memory, a processor, and a

further comprise a fitting for removably attaching a sensor. The device
may further comprise a selector for enabling a specific sensor. The
device may further comprise a lens. The device may further comprise a
display. Such display may be a touch screen panel.

[0053]In an alternative configuration, the invention is a head unit device
for collecting medical data comprising a body, a sensor, and a radio
frequency transmitter. The type of sensor may be selected from the group
comprising still camera, video, sonographic, echographic,
electrocardiographic, peak flow, stethoscopic and audio. The device may
further comprise a switch for turning data capture on and off. The device
may further comprise an analog to digital processor, a lens and/or a
display.

[0054]In another aspect, the invention is a base unit device for
collecting medical data comprising a receiver for communicating with a
head unit, a processor; a display, memory and a control panel. The
display and control may be integrated into a touch screen panel. The
device may further comprise a second transmitter for communicating with a
computer network. The device may further comprise a prompter.

[0055]In another aspect, the invention is a method of collecting patient
data during a physical examination session comprising selecting a first
sensor on a wireless hand-held data collection head unit, capturing
patient data using the first sensor, wirelessly transmitting the data
from the head unit to a base unit and storing the data in digital form.
The method may further comprise selecting a second sensor on the head
unit, capturing patient data using the second sensor, wirelessly
transmitting the data from the head unit to a base unit and storing the
data in digital form. The selecting may be accomplished by removing the
first sensor from the head unit and attaching the second sensor. The data
may be, for example, a video image of the patient's throat or a peak flow
meter reading.

[0056]In another aspect, the invention is a method of conducting a
complete physical examination of a patient comprising recording an audio
track of the entire examination; collecting images of the patients ears,
nose and throat with a hand-held head unit with an otoscopic sensor,
where the head unit transmits the images to a base unit for storage;
collecting sounds of the patient's breathing and heartbeat with a

[0057]In another aspect the invention is a device for enhancing
communication between a physician and a patient comprising a head unit
for collecting new patient data, a base unit for receiving the new data,
a computer program for incorporating new patient data with existing
patient data to create a graphic display of the patient's physiological
condition, and a display unit. The graphic display may a
three-dimensional view of the patient's body highlighting normal and
existing body functions and conditions. The device may further comprise a
control unit for previewing a graphic display before it is shown on the
display unit.

[0058]In yet another aspect the invention comprises a method for enhancing
communication between a physician and a patient. The method comprises
collecting new patient data with a head unit, incorporating the new
patient data with existing patient data, creating a graphic display of
the patient's physiological condition, and displaying the graphic display
to the patient. The graphic display may be a three-dimensional view of
the patient's body highlighting normal and existing body functions and
conditions. The method may further comprise manipulating the graphic
display before displaying the graphic display to the patient.

[0059]Though communication between a head unit and the base unit is
typically wireless, on occasion sensors may be connected to the base unit
by wires. For example, a fixed microphone and camera in an examination
room may be hard wired.

[0060]In another aspect the invention incorporates a medical data storage
system. Data obtained through use of various head units, as well as all
other medical data is digitally stored in individual patient medical
records. Referring to FIG. 5, an individual medical record 700 is shown
schematically. Each medical record includes an interface 702 to a data
network. Each medical record includes a patient identifier 704. A
security code 706 prevents unauthorized access to the record. An access
record 708 keeps track of every attempt to access the medical record,
including the person or account accessing the record, the time of access,
and the information deposited, changed and/or requested.

[0061]Each medical record includes a plurality of data packets, such as
data packet 720. In turn, each data packet 720 is identified by a field
code 730 and a time code 740. The field code identifies the type of data
in the data packet. Such data types may include data gathered from
various head units, such as video images, still images, audio data,
electrocardiogram data, electroencephalogram data, sonogram data, and the
like. Other data types may include test results, DNA sequences, and
diagnostic data from other sources. Still other data types include
diagnoses and treatment records. The time code indicates when the data
was obtained. The time codes and data codes are useful for retrieving
specific data from a medical record, either by request from a human user
or accession by a computer routine.

[0062]In the aspect of a medical data storage system, the invention
includes a computer system coupled to a data network comprising an
interface for accessing the data network and exchanging data signals
therewith; a security mechanism to control access to the system; and a
local persistent memory device for storing multiple individual medical
records, where each individual medical record further comprises a patient
identifier, a patient security code, an access record, and a plurality of
data packages. Each data package may comprise a field code indicating the
type of data stored in the data package; a time code indicating the time
that the data was created; and patient medical data. The type of data
stored in a data package may be selected from the group consisting of
test results, images, DNA sequences, and primary data from diagnostic
devices such as ekg, eeg, oximeter, ultrasound and video.

[0063]In yet another aspect the invention includes a medical diagnosis and
display system. The system may be operated manually by a physician, who
selects data packets from a medical record for direct human examination.
Alternatively the system may be operated by one or more pattern
recognition routines that access data packets and compare them against a
database holding data describing both normal physiological conditions and
clinical pathology states. Such a system may be operated by base unit 200
or other computers in the network 300.

[0064]In this aspect the invention includes a medical diagnosis and
display system comprising a memory device for storing an individual
medical record having a plurality of data packages; a database including
data describing normal physiological conditions and clinical pathology
states; a processor; a control panel; a pattern recognition routine for
accessing data packages and comparing them against the database; and a
display.

[0065]In another aspect the invention includes a method of performing a
medical diagnosis comprising selecting a pattern recognition routine;
accessing an individual medical record; accessing a database including
data describing normal physiological conditions and clinical pathology
states; comparing data in the individual medical record against data in
the database; and observing the output of the routine.

[0066]In record capture, recording, reporting, and diagnosis modes, the
system utilizes pattern recognition routines for where, when, and what a
given pathological state exists. The system also tracks the clinical
condition and therapeutic response compared at each point in time in a
three-dimensional matrix of a body, with a point-to-point corresponding
site of quantity and quality of lesion and/or physiologic state which can
be captured and displayed easily for evaluation, comparison, storage,
research and development of new diagnostic and therapeutic alternatives.

[0067]In another aspect, the invention comprises a system that integrates
and displays medical data, as well as a method for integrating and
displaying medical data. FIG. 6 depicts a female human FIG. 800 as
displayed by the system. The system integrates data from various sources
and, where possible, maps the data in three dimensions for diagnostic
purposes as well as for enhancing doctor-patient communications. In
practice, the display can be manipulated by a user to provide various
perspectives. In this example, the FIG. 800 represents a breast cancer
patient with a tumor 820.

[0068]All individual patient data since birth may be incorporated into the
display system, whether obtained directly from the head unit 100 or from
other sources. Such data includes information that readily allows
depiction in three dimensions such as multiperspective still and video
images, MRI scans, PET scans, X-rays, and the like. Information that is
not readily displayed in three dimensions can also be displayed by the
system. Such information includes lab tests, pathology reports, pathology
images, treatment records, family histories, and the like.

[0069]When viewing the display of human FIG. 800, the user may zoom in on
the area of the tumor 800. The display may be rotated to observe the
tumor area from various perspectives. Overlays of systems (e.g., lymph)
and tissues may be added to or removed from the display by the user. Two
dimension cross-sections may be displayed. The user can also call all
other patient data for display. Changes in physical and physiological
conditions over time can also be displayed over time. For example, in the
case of a breast cancer patient, a physician can view and display the
condition over time. X-rays of breast examinations, stored in the system
over a period of years, may be displayed chronologically. Records of past
and current medical examinations, laboratory tests, pathology reports,
treatment records, and the like can also be called up and displayed for
review. The system can integrate and display all data for the entire
human body, or any part thereof.

[0070]In another aspect the invention is a device for diagnosing ear
infections where the physician and patient are physically separated, the
device comprising a base unit and a head unit, where the base unit
comprises a first transceiver, memory, and a processor. The head unit
comprises an otoscope sensor, and a second transceiver for wireless
communication with the base unit. The first transceiver of the head unit
may be a first programmable communication device, e.g., a cell phone. The
transceiver of the head unit and the otoscope sensor preferably
communicate wirelessly, though wires may be used. The first programmable
communication device may comprise a display programmed to allow viewing
of images detected by the otoscope sensor. The device may further
comprise an individual patient medical record. The device may further
comprise a medical diagnosis and display system. The device may further
comprise a pattern recognition routine for diagnosing ear infections. The
device may further comprise a second programmable communication device
for receiving images from the base unit.

[0071]In another aspect the invention is a method of diagnosing an ear
infection, the method comprising imaging a patient's ear drum using an
otoscope sensor; wirelessly transmitting the image of the ear drum from
the sensor to a first programmable communication device; transmitting the
image of the ear drum from the first programmable communication device to
a remote base unit; and analyzing the image to determine a course of
treatment. Such analyzing may include a computerized pattern recognition
routine. The method may further comprise storing the images in an
individual patient medical record. The method may further comprise
displaying the image of the ear drum on a display on the first
programmable communication device. The method may further comprise
transmitting the image from the base unit to a second programmable
communication device and displaying the image on the second programmable
communication device.

[0072]In another aspect the invention includes an otoscope sensor head
comprising a programmable communication device having a display; and an
otoscope sensor, where the device and the sensor communicate wirelessly.

[0073]While preferred embodiments of the present invention have been
described, those skilled in the art will recognize that other and further
changes and modifications can be made without departing from the spirit
of the invention, and all such changes and modifications should be
understood to fall within the scope of the invention.
